Decision models alongside generative AI
Not every step in an agentic workflow needs a model that writes text. Decision models return fast, typed answers: yes or no with a probability, a choice from fixed options or a score. The Automation Group uses them alongside generative models.

Three flavours
Deciding instead of generating.
Decision models answer bounded questions with typed outcomes and probabilities. Code stays in control; the model supplies the judgment.
02N° 02
OpenAI Decisions API
In public beta since October 2026: predicates, choices and scores over text and images via a dedicated endpoint.

Laya (open source)
An open-source, multilingual decision model under the Apache 2.0 licence that you can host yourself.
04N° 04
Generative where needed
For explanations, summaries and reasoning a generative model remains the right choice. The craft is in the combination.
Where we use them
Route, prioritise, verify.
- 01
Route
Send an incoming request to the right agent, tool or department.
- 02
Prioritise and score
Assess tickets, documents or leads against fixed criteria.
- 03
Verify
Check a generative agent's output before it moves on.
- 04
Escalate
When confidence is low, hand the decision to a person or a heavier model.
Frequently asked questions
Decision models alongside generative AI
What is a decision model?+
A model that doesn't generate text but returns a typed answer such as a choice, score or probability. The Automation Group uses them for steps that need a fast and verifiable judgment.
Which should I pick: Jev, OpenAI Decisions or Laya?+
That depends on your requirements for hosting, languages, cost and accuracy on your own data. The Automation Group tests options on representative examples before choosing.
Do decision models replace generative AI?+
No. They complement each other: decision models for bounded judgments, generative models for text and reasoning.

Which decisions could your workflow make faster?
Together we look at which steps deserve a decision model and which a generative one.
